oALENDERiNG-MACHINE- SPCIFICATION forming part of Letters Patent No. 275,676, dated April 10, 1 883.

l Application tiled March 7, 1883. (No model.)

To all when@ it may concern Be it known that I, MICHAEL A.W.LoU1s, of Washington, in the District of Columbia,

Ahave .invented certain new and useful Improvements in Galendering-Machines; and Ido hereby declare that the following is a full, clear, and exact; description thereof.

My invention relates to machines for drying and calendering printed paper; and it consists in certain attachments for guiding the sheets from the calendering-rolls to the discharge-table, as will be fully described hereinafter.

In the drawings, Figure 1 is a side View ot' my attachments applied to a calendering-machine, which latter is shown in dotted lines. Fig. 2 is a perspective view of one ot' my attachments. Figs. 3 and 4 are details, and Fig. 5 illustrates a slightly modified form of my device.

AA are the calendering-rolls, similar in arrangement to those in patent to Henry J. Gill,- May 11, 1875, No. 163,180.

B B' are rods that extend from one side of the machine to the other, and lie just below the adjacent faces of the rolls A A. These rods are geared or belted to the-machinery by which the rollers A A are revolved, so that the roll A and rod B will revolve in one and the same direction, while the roll A' and rod B will revolve in the opposite direction. The rods B B', like similar rods in the Gill patent, are provided with circular brushes, and as they turn in opposite directions the brushes grasp the paper C between them and draw it down over the roll A and from between it and the roll A; and heretofore these brushes have delivered the paper onto a hinged rack having fingers that were supposed to guide it (the paper) on its way to the delivering-apron; but, having found that this rack performed its office imperfectly, I conceived the idea of connecting the shafts B and c by an apron composed of endless tapes, each one ot' which depends from a groove in a loose collar, b, on shaft B down to and around the shaft c, and in this way I provide a bridge or carrier that will support the paper from the time it leaves the brushes until it reaches the delivery-apron; and to care for it then I provide rollers F, that take the paper as it leaves the apron E and'press it down upon the delivery-apron as it passes on' to the delivery-table.

To make the action of the tapes E more certain I may provide another apron, E', that, like apron E, is composed of endless tapes. These tapes encompass the rods B B2, and are shown inFig.5,andlie soclosetothe tapesEasto clamp the paper between the two aprons, and consequently the paper cannot rumple or be drawn out ot' its course by the electricity, which gen*- erally creates so'much disturbance in this class ot' machines, especially in winter.

'Ille apron E may be dispensed with with very good results; but where it is used it will be necessary to set the rod c farther back, so

as to leave room for the rod B2 between the apron E and the reservoir Gr, all as shown in Fig. 5. I propose to make the bearings of all the rollers adjustable.

To guide the paper from the apron E tothe delivery apron D, I provide rollers F, one ot' which, with its hanger, I will now describe. F is the roller bracket, having jaws F2, one of which is made removable; or it may be hinged to the bracket to admit of the removal and replacement of the roller, and in these jaws the axle of the roller F has its bearings. The rear end of the bracket, or that opposite the jaws F2, has a round threaded extension, which carries a nut, F4, channeled, as shown, to take the arms Il2 ot' the bifurcated ange on outer end of the horizontal portion H ofthe hanger that suspends the bracket F in position. The hanger is composed of a vertical and a horizontal portion or strap, and the lower end of the vertical portion HJ is squared out where it joins the horizontal portion to allow the bracket Fto pass through it, so as to lie along the entire length ot' the horizontal portion H, the curved inner end of which lies up under a shonlder,f, in bracket F', so as to be out of the way and not be liable to impede the progress ofthe paper as it leaves the roller F, or to catch it should it curl up, and as the arms H2 of the portion H of the hanger engage with the channel in the nut FJt the bracket may be adjusted back and forward'by turning the nut F4. rlhe portion II ot' the hanger has a iiange, h, that carries a set-screw, c', and has a strap, the top of which is flanged, as at h2. The maln portion of strap h' is slotted at j to receive'a setscrewqjz, by which it is secured to the portion H of the hanger, and at j to take a steadyingpin that projects out from the portion H. The

ICO

flange his designed to take under the rim g of 1 to the inner supporting rod of the deliverythe reservoir, and the flange h2 to take over it, and the hanger is tightened in place by the setscrew i. Now, the bracket may be adjusted up and down by loosening set-screw jz and manipulating,` set-screw i', or by the turning of a setscrew, 7., which, passingr down through the outer portion ofthebracketF,rests upon thestrapH.

The adjust-ability ot' my roller F adapts it for paper of varying thicknesses and machines of varying sizes.

I may in some instances use only one roller F, but prefer to use tivo or more.

I do not confine myself to the precise construction herein described.

The rollers F are to be made of vulcanized rubber, glass, or any other non-conducting ma terial.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, with the brush-rods of a paper drying and calendering machine, of an endless apron leading from one of them down apron, as set forth.

2. The combination, with one ot' the brushrods, of an endless apron leading from it to the inner rod of the deliverytable, and a roller su spended above the delivery-apron, as set forth.

3. The combination, with rods B, B', B2, and 3o c, of endless aprons E, E', and D, as set forth.

4. In combination with the roller F, an adjustable bracket and hanger, as set forth.

5. The roller F and its bracket, in combination with the hanger H H', made adjustable, as 35 set forth.

G. The brackethavingreducedscrew-threaded end, in combination with the hanger havingA horizontal portion flanged at H2, as set forth.

In testimony that I claim the foregoing I 4o have hereunto set my hand, on this 5th day of March, 1883, in the presence of two witnesses.
